This PR includes changes in the taylor.py file. I have added 2 MultiPoint Taylor expansions that (in addition to the 1st-order conditions) satisfy:

SphericalTaylor2 : Satisfies previous point function value, i.e. g_tilde(xold1) = g(xold1)
NonSphericalTaylor2 : Satisfies previous point gradient value, i.e. dg_tilde(xold1) = dg(xold1)

Made another one where I corrected the imports according to @MaxvdKolk's input.
